I am porting my Last 15 searches hack from 3.0 to 3.5.
Right now it handles the permissions fine as the user can not get into a forum that they aren't supposed to. But the word they searched for WILL show up in the Last 15 Searches listing even though it is in a forum they can't access. I wouold like it to not show up in the listing for any forum that they don't have access to so they can't somehow stumble onto something that they really shouldn't.
And also, it shows the threads it is in instead of the individual posts. I would like to see it just display the posts.
